IN THE CLAIMS:

Quarles & Brady - TUC

Art Unit ] 742

Please enter the following claims:

L (Original) A method for reducing the formation of biofiJm deposits on a wall in a water
system comprising the steps of:

providing a capacitive electrostatic generator adapted to create an electrostatic field;

immersing said electrostatic generator in a body of water in the water system, the water
system being connected to an electrical ground relative to an electromotive force available for
energizing the electrostatic generator; and

energizing said electrostatic generator with said electromotive force, such that a
corresponding electrostatic field is created between said generator immersed in the water system
and said electrical ground without measurable current leakage in the body of water;

wherein said capacitive electrostatic generator comprises a vitrified ceramic tube of
unibody construction having an integrally-sealed end defining an inner cavity with an inner wall;
conductive material contained within said inner cavity and disposed in intimate contact with said
inner wall; electrically-insulated sealing means for providing hermetic closure to said inner
cavity; and electrical means for energizing said conductive material with a static electromotive
force.

2. (Original) The method of Claim 1, wherein said voltage is greater than about 10,000 volts
DC.
